  • Patent number: 8738378
    Abstract: A speech recognition apparatus includes a speech collating unit that calculates similarities at each time between a feature amount converted by a speech analyzing unit and a word model generated by a word model generating unit. The speech collating unit extracts a word model from word models generated by the word model generating unit, whose minimum similarity among similarities at each time or whose overall similarity obtained from similarities at each time satisfies a second threshold value condition, and whose similarity at each time in a section among vocalization sections of utterance speech and corresponding to either a phoneme or a phoneme string associated with a first threshold value condition satisfies the first threshold value condition, and outputs as a recognition result the recognized word corresponding to the extracted word model.

  • Patent number: 7991614
    Abstract: A speech recognition system includes the following: a feature calculating unit; a sound level calculating unit that calculates an input sound level in each frame; a decoding unit that matches the feature of each frame with an acoustic model and a linguistic model, and outputs a recognized word sequence; a start-point detector that determines a start frame of a speech section based on a reference value; an end-point detector that determines an end frame of the speech section based on a reference value; and a reference value updating unit that updates the reference value in accordance with variations in the input sound level. The start-point detector updates the start frame every time the reference value is updated. The decoding unit starts matching before being notified of the end frame and corrects the matching results every time it is notified of the start frame. The speech recognition system can suppress a delay in response time while performing speech recognition based on a proper speech section.

  • Patent number: 7962338
    Abstract: When the degree of similarity of the recognition candidates is greater than the second threshold value, the speech verification unit outputs the recognition candidates as a recognition result, and when the degree of similarity of the recognition candidates is smaller than the second threshold value, it outputs the recognition candidates as a recognition result if the degree of similarity of the recognition candidates is greater than the first threshold value and, at the same time, the degree of similarity of the recognition candidates is greater than the degree of similarity of the rejection candidates. It should be noted that the first threshold value is a measure used for rejecting input speech. The second threshold value is larger than the first threshold value and is used as a measure for outputting recognition candidates as a recognition result.

  • Patent number: 7672846
    Abstract: A voice recognition system and a voice processing system in which a self-repair utterance can be inputted and recognized accurately, as in a conversation in which a human user makes a self-repair utterance. A signal processing unit converts speech voice data into a feature, a voice section detecting unit detects voice sections in the speech voice data, and a priority determining unit selects a voice section that includes a self-repair utterance from among the voice sections according to a priority criterion without using any result of recognizing a speech vocabulary sequence. Priority criteria can include a length of the voice section, signal to noise ratio, chronological order of the voice section as well as speech speed. A decoder calculates a matching score with a recognition vocabulary using the feature of the voice section and an acoustic model.
